wifi: iwlwifi: mvm: remove one queue sync on BA session stop

Browse Source 
As documented in the comment, this queue sync was here to
ensure that an async IWL_MVM_RXQ_NSSN_SYNC queue sync won't
race with setting up a new BA session with the same BAID.
However, we no longer do IWL_MVM_RXQ_NSSN_SYNC queue sync,
so we can remove this as well.
